Image recording apparatus and parameter setting method

Abstract

An image recording apparatus includes a recording head, a recording-position information obtaining unit configured to obtain recording position information of a plurality of recording elements a plurality of times at an interval of an arbitrary period, a recording-position chronological change information calculating unit configured to calculate chronological change information of the recording position for each recording element, a medium type specifying unit configured to specify a type of a medium using the chronological change information of the recording position for each recording element, and a parameter setting unit configured to automatically set at least either one of a recording parameter and an abnormality detection parameter in correspondence with the specified type of medium.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2016-042389, filed on Mar. 4, 2016. The above application is hereby expressly incorporated by reference, in its entirety, into the present application.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present invention relates to an image recording apparatus and a parameter setting method and particularly to a control technology of a recording head.[0004]Description of the Related Art[0005]In an image recording apparatus including a recording head, when a medium or a base material to be used is changed, a method of setting a recording parameter such as a recording procedure or an ejection amount or the like is known. In an image recording apparatus with a single path, not only the recording parameter such as the recording procedure or the ejection amount or the like but also an abnormality detection parameter such as a threshold ...

AI Technical Summary

Benefits of technology

This patent describes a method for identifying the type of medium used in a recording device by analyzing the changes in recording position over time. This helps ensure that the type of medium is not dependent upon the user's settings. It also automatically sets the recording parameters and abnormality detection parameters, improving usability. Additionally, a threshold value used to identify the medium is constantly accurate, regardless of changes in the recording head's state. Overall, this patent provides a more reliable and user-friendly way to identify the type of medium used in a recording device.

Problems solved by technology

However, if the type of the medium or the type of the base material is set and the parameters such as the recording procedure, the ejection amount or the detection threshold value or the like is set by a user's manual input of the information on the medium or the base material in the image recording apparatus, setting of the type of the medium or the type of the base material depends on the user, and the user can input wrong information on the type of the medium or the type of the base material.

Moreover, unless the detection threshold value is set properly, the recording element which is not the abnormal recording element is detected as the abnormal recording element, and there is a concern of an increase in waste sheets caused by an increase in the abnormal recording elements or excessive correction or insufficient correction caused by an increase in unnecessary masks for abnormal recording element correction.

Even if the user can arbitrarily set the detection threshold value or the like, unless a proper detection threshold value is set, there is a concern of an increase in waste sheets caused by an increase in the abnormal recording elements or abnormal correction caused by an increase in unnecessary masks for correction.
